Definitions

  • the present invention is in the field of cosmetics and relates to a product for the oxidative color change of keratinic fibers, in particular human hair, which comprises a packaged in an oxidant-containing composition.
  • the oxidizing agent-containing composition contains at least one Cs-Cso alcohol, at least one nonionic surfactant and at least one anionic surfactant.
  • the packaging is a packaging made of a special multilayer composite film system, the wall of which comprises at least two polymeric layers and a Barierre layer.
  • the barrier layer has a natural SharePointr für for gases and water vapor.
  • the barrier layer includes a metal.
  • oxidative color-change agents are usually employed.
  • oxidation colorants For permanent, intensive colorations with corresponding fastness properties, so-called oxidation colorants are used.
  • Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components, which under the influence of oxidants - usually hydrogen peroxide - form the actual dyes among each other. Oxidation dyes are characterized by excellent, long-lasting staining results.
  • Oxidative color changing agents usually come on the market in the form of two-component compositions, in which two different preparations are packaged separately in two separate packages and are mixed together only shortly before use.
  • the first preparation is a - usually acidified for stability reasons - formulation containing as oxidizing agent, for example, hydrogen peroxide in concentrations of 1, 5 to 12 wt .-%.
  • the oxidizing agent formulation is usually in the form of an emulsion or dispersion and is usually provided in a plastic bottle with reclosable outlet opening (developer bottle).
  • This oxidizer formulation is mixed with a second formulation before use.
  • This second preparation is an alkaline formulation which is often in the form of a cream or gel and which also contains at least one oxidation dye precursor if, at the same time as brightening, a color change is desired.
  • This second preparation can be provided for example in the form of a tube or in the form of a plastic or glass container.
  • the second preparation which contains the alkalizing agent and / or the oxidation dye precursors, transferred from the tube or container in the developer bottle and then mixed by shaking with the already in the developer bottle hydrogen peroxide preparation.
  • the application mixture is prepared in the developer bottle.
  • the application on the hair then takes place via a small nozzle or outlet opening on the head of the developer bottle.
  • the spout is opened after spillage, and the application mixture can be removed by squeezing the flexible developer bottle.
  • the use of the developer bottle requires a certain amount of routine from the user, so that some users prefer to make the application mixture in a mixing bowl and apply it with a brush.
  • the application mixture is then removed via the brush from the mixing bowl.
  • the use of a voluminous and expensive developer bottle is not necessary, and it is still sought after inexpensive and material-saving packaging forms for the oxidant preparation.
  • packages in the form of bags or pouches which as a rule are made of plastic films or even metal foils, are suitable as inexpensive packaging forms with low material consumption.
  • Such a packaging can be produced, for example, by gluing or hot-pressing two superimposed plastic films, the adhesion taking place on all edges of the films.
  • the interior of the packaging produced by bonding ie the plastic bag
  • the opening of the package can be done by tearing or cutting the plastic bag.
  • Oxidizing agents are highly reactive substances which, depending on the storage conditions and, if appropriate, the presence of decomposing impurities, decompose in small amounts to form oxygen (i.e., gas).
  • developer bottles known from the prior art are filled with the oxidizing agent composition only a maximum of half, usually only one third, of their internal volume.
  • developer bottles are made of polyethylene. Since polyethylene is permeable to both water vapor and other gases, there is no or very little overpressure in the developer bottle.
  • developer bottles are usually provided with stable, thick walls and a sturdy screw closure, so that the diffusion of water vapor or gases through the thickness of the walls is reduced and a slight pressure increase occurring within the bottle has no negative effects.
  • bag-shaped packages are, however, usually filled completely with the liquid preparation, and in the filled bag there is virtually no supernatant airspace.
  • packages should be flexible, and upon opening (e.g., tearing or slicing), there should be no uncontrolled discharge of the preparation. For this reason, in the packaging of liquid preparations, the emergence of overpressure in the packaging should be avoided as far as possible.
  • an oxidizing agent composition is present in such a packaging, the gas (oxygen) produced during storage may cause the packaging to expand. Since the edges of the package are usually only glued, a strong swelling at worst leads to bursting of the packaging. For these reasons, when storing oxidizer-containing compositions, the choice of the film material constituting the package is of great importance.
  • Packaging made of pure plastic, such as polyethylene or polypropylene, is permeable to both water vapor and gases.
  • oxidant-containing preparations in a package made of polyethylene or polypropylene, therefore, no inflation of the packaging.
  • due to the high permeability of the relatively thin film of the packaging to water vapor decreases the water content of the preparation. If the preparation is stored in the packaging for a few weeks to months, the loss of water exceeds the maximum permitted for sufficient storage stability.
  • the film materials are of great importance, especially in the storage of a multicomponent system, since substances from the multicomponent system can diffuse into the films and can promote a detachment of layers which form the film.
  • the choice of the components of a hydrogen peroxide-containing formulation thus also has an influence on the choice of packaging.
  • the object of the present application was to package hydrogen peroxide-containing formulations in such a way that the mechanical strength of the packaging is sufficiently large to allow safe storage, but easy accessibility to the ingredients is ensured.
  • oxidizer-containing compositions can be packaged in which the water vapor permeability is low and puffing can thereby be reduced by allowing the film a certain degree of oxygen permeability.
  • the films consist of a special composite film system and additionally have a barrier layer.
  • At least one packaging comprising at least one multilayer film (F) which contains at least one first polymer layer (P1), at least one second polymer layer (P2) and at least one barrier layer (BS), and
  • the first polymer layer (P1) is formed of polyethylene terephthalate or polyethylene naphthalate, especially polyethylene terephthalate
  • the second polymer layer (P2) is formed of a polyolefin, in particular polyethylene
  • the barrier layer (BS) is formed from metallized, oriented polypropylene.
  • Keratinic fibers, keratin-containing fibers or keratin fibers are understood to mean furs, wool, feathers and, in particular, human hair.
  • compositions according to the invention are primarily suitable for lightening and dyeing keratin fibers, in principle, there is nothing to prevent their use in other fields as well.
  • the product according to the invention is a product for the oxidative color change of keratinic fibers, i. a product used on the human head to achieve oxidative coloring, brightening, bleaching, bleaching or hair shading.
  • shade is understood to mean a coloring in which the color result is lighter than the original hair color.
  • That the product is to be used "to change the natural color” is intended to mean that the product either comprises only an oxidizing agent for bonding, or that the product comprises an oxidizing agent used with a non-invention coupler to cause a color change or that the product is used with a non-invention dye for further tinting.
  • the term "packaging” is understood to mean a packaging which is preferably present in the form of a sachet.
  • a sachet is a small package in bag or bag form, which is often used in the packaging of cosmetics.
  • the capacity of the packaging, in particular of the sachet can be, for example, 5 to 1000 ml, preferably 10 to 200 ml and particularly preferably 20 to 50 ml.
  • a multilayer film (F) in the context of the present invention is understood to mean a thin, areal and windable web of the at least one polymer layer (P1) and the at least one polymer layer (P2). This multilayer film (F) forms the wall of the package (VP).
  • the packaging additionally contains a barrier layer (BS), which selectively allows or reduces the passage of water vapor and other gases, such as oxygen.
  • BS barrier layer
  • the cosmetic product according to the invention comprises as the first component a packaging (VP) which comprises at least one multilayer film (F).
  • This film contains at least one first polymer layer (P1), at least one second polymer layer (P2) and at least one barrier layer (BS).
  • VP packaging
  • BS barrier layer
  • such packaging is usually produced by gluing, pressing or welding two superposed pieces of film (the packaging (VP) being filled simultaneously with the cosmetic composition (KM) ), ie such a package is closed at all edges.
  • This packaging can be opened, for example, by tearing or cutting open.
  • the thickness of the multilayer film (F) determines the mechanical properties and the strength of the films. It should in this case be designed so that a sufficient mechanical stability is present, but at the same time the film (F) - and thus the packaging produced from the film (VP) - is so flexible that a complete removal of the cosmetic composition (KM) the opened package (VP) is made possible by compression or extrusion. These requirements are met by a film when the film (F) has a certain total thickness. Preferred embodiments of the present invention are therefore characterized in that the at least one multilayer film has a total thickness of 28 pm to 220 gm, preferably from 52 pm to 180 pm, more preferably from 80 pm to 140 pm. For the purposes of the present invention, the total thickness of the film (F) is understood to be the sum of the thicknesses of all individual layers of which the film (F) consists.
  • the arrangement of layers (P1), (P2) and (BS) within the multilayer film (F) may be different. Furthermore, it is also possible for the film (F) to comprise further layers in addition to the previously mentioned layers. In addition, it is advantageous according to the invention if all of the above-mentioned layers are each oriented parallel to the surfaces of the film (F), ie all layers have the same orientation. If the multilayer film (F) contains the above-described three layers (P1), (P2) and (BS), the following arrangements of the layers would be possible (from the interior (in contact with the cosmetic composition (KM)) to the outside):
  • the barrier layer (BS) is arranged between the first polymer layer (P1) and the second polymer layer (P2), wherein the second polymer layer (P2) is located on the outside of the packaging.
  • the multilayer film (F) consists of three layers, the layer (P1) being in the innermost position and in contact with the cosmetic composition (KM).
  • the layer (P1) is in contact with the barrier layer (BS), and the barrier layer (BS) in turn makes contact with the layer (P2).
  • the layers (P1) and (P2) do not adjoin one another but are separated by the barrier layer (BS).
  • the - often very thin - barrier layer (BS) is located neither on the inner nor on the outer surface of the multilayer film (F), but in the direction of the inside through the polymeric layer (P1) and in Protected from the outside by the polymeric layer (P2). In this way, in this arrangement, a mechanical abrasion or mechanical destruction of the barrier layer (BS) are best avoided. It is therefore advantageous in the context of the present invention for the at least one multilayer film (F) to contain the at least one barrier layer (BS) between the at least one first polymer layer (P1) and the at least one second polymer layer (P2).
  • the barrier layer (BS) is likewise arranged between the two polymer layers P1 and P2, but the first polymer layer (P1) is located on the outside of the packaging.
  • the outer side of the packaging is understood to mean that side of the packaging which does not come into contact with the cosmetic composition (CM) but with the environment.
  • CM cosmetic composition
  • the first polymeric material of the first layer (P1) according to the invention is a polyester. This material may be a polymer type layer or a polymer blend layer.
  • the at least one first polymer layer (P1) is formed from polyethylene terephthalate or polyethylene naphthalate, in particular from polyethylene terephthalate.
  • the term "formed" is understood according to the invention that the polymer layer at least 70 wt .-%, preferably at least 80 wt .-%, preferably at least 90 wt .-%, in particular at least 99 wt .-%, jewiels based on the total weight of the polymer layer (P1), the previously mentioned compounds.
  • Polyethylene terephthalate is a polymer from the group of polyesters.
  • the production of polyethylene terephthalate can be carried out, for example, by transesterification of dimethyl terephthalate with ethylene glycol at higher temperatures. In this transesterification reaction, methanol is split off, which is removed by distillation. The resulting bis (2-hydroxyethyl) - terephthalate is converted by polycondensation to PET, which again produces ethylene glycol.
